05 Jeep 5.7 complete setup
The LA motor is an excellent motor, and they can make great power, I'm not trying to knock it, I had a 340 Duster and it was the coolest car I've ever owned. I'm hoping my 6.1L Hemi Dart will live up to my inner car fantasies, and be a worthy successor to my long lost Duster.
So you're idea about finding the hidden costs is KEY to figuring out if you want to do this swap or not.
You've got to root out those hidden costs before you start buying parts.
Sounds to me like you've got a pretty good handle on the situation, all you need to do is sharpen your pencil.
